Avatar m tn Two studies have been carried out to assess the effect of food (ie, a high-fat breakfast) on the bioavailability of a SINGLE oral dose of ribavirin. An initial study by ICN Pharmaceuticals, Inc. showed MINOR EFFECTS on bioavailability, but a 33% increase in Tmax (Time to Maximum Concentration)" In other words, a high-fat breakfast (54 grams of fat) slowed the absorption of Ribavirin by 33%.
Avatar n tn Atorvastatin is supposed to be one of the two most effective statins in lowing cholesterol so you are on a good one. Bioavailability is how well a med is absorbed and used by the body and bioavailability varies among the statins. It's actually a desired thing. The liver is the target organ so if it is slowed down in the liver (where this happens), it's in the target organ. But honestly, that is hard for me to understand.

Avatar f tn Effects of Food and Antacid on Bioavailability Two studies have been carried out to assess the effect of food (ie, a high-fat breakfast) on the bioavailability of single oral doses of ribavirin (Table 2). An initial study by ICN Pharmaceuticals, Inc. (Costa Mesa, Calif)[19] showed minor effects on bioavailability, but a 33% increase in Tmax.
5281642 tn?1366917055 Hi! I just want to ask if someone use a drugs (amphetamine-speed) before he\she performed cunnilingus, is this increase the risk of HIV. I don't mean having a meth mouth are realy bad oral hygiene. I find this site very helpful. Thanks for your time and greetings from Bulgaria.
Avatar f tn Also as a side note, Opana oral bioavailability is actually very low. Lower than morphine I believe the bioavailability is around 10 percent. However, if you reach your optimal dose, bioavailability matters little. I see that this post is from October 2011. But since I have this typed, I'll post anyway :) Good luck and gentle hugs.

An initial study by ICN Pharmaceuticals, Inc. showed MINOR EFFECTS on bioavailability, but a 33% increase in Tmax (Time to Maximum Concentration)" That means it took longer to reach the maximum Riba concentration after taking one dose!!! Or to make it more clear, a high-fat breakfast SLOWED THE ABSORPTION OF RIBAVIRIN BY 33%!!!!!!!

Avatar m tn Effects of Food on Oral Absorption VICTRELIS should be administered with food. Food enhanced the exposure of boceprevir by up to 65% at the 800 mg three times daily dose, relative to the fasting state. The bioavailability of boceprevir was similar regardless of meal type (e.g., high-fat vs. low-fat) or whether taken 5 minutes prior to eating, during a meal, or immediately following completion of the meal.
1861446 tn?1320445285 Hi ppl. I've been on amphetamine since I was 14. I'm 28 this month. That's half of my life. I've been working hard the past 12 months to gain funding for rehab. I'm curious if anyone else has a similar story to me and even more curious to know whether life can actually feel worth living ever again..
Avatar m tn Adderal is an amphetamine, but it shouldn't test as "meth" in a good drug screen. I happen to have a urine drug screen form right here, you can test "negative". Or positive for cannabinoids, cocaine, amphetamine, methamphetamine, opiates, etc. The amphetamine and meth are two different "check boxes", and you should have tested positive for amphetamine. If you have a prescription in your name that shouldn't be a problem. Best wishes.
Avatar n tn I have two sons with ADHD. The 'upper meds' 'boots' is talking about are the ones the are in the amphetamine class...extremely addictive, if abused. Ritilan, Adderal, Focalin, Daytrana are a few more in that class. He/she also added that they are an recovering addict, so I assume that they have abused, or are afraid that they will abuse these meds. Boots: I know of one that isn't an 'upper'. It's called 'Concerta'.
Avatar f tn Adderall is an amphetamine. And it's addictive much like cocaine is. Maybe someone with personal experience with cocaine could jump in? Look up 'amphetamine psychosis' and 'dopamine hypothesis of psychosis/schizophrenia' to see how extended use of amphetamine can change a person psychologically. Becoming violent is only the tip of the iceberg of everything it can cause to happen to a person emotionally.
Avatar f tn It's not okay to take someone else medications but well, Vyvanse is a stimulant in the category of amphetamines. Not suggested for anxiety but can be helpful for depression. Wellbutrin could be a bit more suitable for you with less side-effects if dopamine and norepinephrine is a problem in your depression/anxiety. Depression often leads to anxiety so yeah maybe when you took Vyvanse you had euphoric effects similar to those with amphetamine ''speed''.
Avatar m tn My pulse is exceptionally weak and my blood pressure is 156/90 after taking one (1) 500mg Naproxen and an amphetamine. I went and got my blood pressure checked, as well as my resting heart rate. The nurse never actually tried to feel my pulse, though. So I came home and I am very worried about how weak my pulse is. Has anybody heard weather or not taking Naproxen with an amphetamine can be harmful because it is not in the drug facts and I cannot find anything about it online either.
Avatar m tn There have been several studies that showed the bioavailability of ribavirin increased with a high fat meal. The question is how much fat. My guess is to take with some fat (10 g?), not the 20 g needed for Inc. This has been discussed frequently on the forum if you care to search more. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1804105/ Effect of Food on Absorption of Ribavirin Bioavailability of a single oral dose of Ribavirin was increased by co-administration with a high-fat meal.
Avatar f tn Are there any anti depressants or non stimulant/amphetamine meds that will help with the sleep attacks & day time drowsiness associated with narcolepsy? I'm a naturally anxious person.. and going on something like Adderall or Ritalin is out of the question... unless maybe if I have to drive somewhere that day. Is there any way to correct the condition, like with antidepresants?
Avatar f tn I eventually quit snorting my oxy80s and started doing the majority of mine rectally (dissolving in water, then using 1mL oral syringe) because it increases the bioavailability of almost all opiates by a wide margin, and basically is much better/efficient if your looking for a high like I always was, rather than just pain relief. And it sounds like you might be (no offense).
Avatar f tn It is an effective antiviral agent but is limited by low oral bioavailability, renal toxicity and poor cell penetration. According to the company, CMX157's novel formulation enables it to deliver high intracellular concentrations of tenofovir thereby making it more effective at permanently suppressing HBV replication than existing drugs.
Avatar f tn Blood tests are not accurate for testing the active bioavailability of sex hormones in the cells and tissues. They only test what's in the blood stream. They aren't accurate for testing when a patient is using bioidentical topical creams. I've had two holistic doctors tell me this and have read numerous articles about which testing is correct depending on which type of hormones you're taking.
